Title (EN) FLUX DAM ASSEMBLY AND METHOD
(FR) ENSEMBLE DE BARRIERES DE FLUX ET PROCEDE
Abstract: front page image
(EN)The flux dams used to form mounds of granular flux in submerged arc welding deteriorate rapidly because they are subjected to elevated temperatures and high heat. These flux dams also twist and distort creating gaps. Granular flux bleeds through these gaps. Flux is wasted and the welding arc may be exposed to the atmosphere. Flux dams are also awkward to move and slow production down. The apparatus and method disclosed herein overcome these problems by utilizing an elongate flux dam (19) that is stationary during welding and which extends for the length of the weld. The flux dam (19) is mounted on a heat exchanger (24) by a mounting plate (21) that minimizes thermal distortion of the flux dam (19). The heat exchanger (24), the mounting plate (21), and the flux dam (19) are pivotally connected to a support arm (26) that is mounted for motion about the platform (6) on a pivot point (32).
(FR)Les barrieres de flux utilisees pour former des monticules de flux annulaires dans des postes de soudage a l"arc submerge se deteriorent rapidement du fait qu"elles sont soumises a des temperatures elevees. En outre ces barrieres de flux se tordent et se deforment en formant des interstices. Le flux granulaire s"ecoule au travers de ces interstices. Le flux est gaspille et l"arc de soudage peut se trouver expose a l"atmosphere. Le deplacement des barrieres de flux est en outre peu commode, ce qui ralentit la production. Le dispositif et le procede decrits permettent de resoudre ces problemes en utilisant une barriere de flux allongee (19) immobile pendant le soudage et s"etendant sur la longueur du soudage. La barriere de flux (19) est montee sur un echangeur de chaleur (24) au moyen d"une plaque de montage (21) reduisant au minimum la distorsion thermique de la barriere (19). L"echangeur de chaleur (24), la plaque de montage (21), et la barriere (19) sont connectes de maniere pivotante a un bras de support (26) monte de maniere a pouvoir tourner autour de la plateforme (6) sur un point de pivot (32).
